\ IMPROVEMENT IN sEAI'.Loci:s `Fon BAGe.

The Schedule referred to in these Letters Patent making part oi thesame.

lBe it known that I, JOHN DEWE, of the' `city of Toronto, in the countyof- York, Province of Ontario,

Canada, have invented a new and useful Improvement A in Seal-Locks and Ido -herebydeclare that the'foly lowing is a full, clear, and exactdescriptionv of the construction and operation of the saine, referencebeingl had to the annexed drawings, making a part of this specification,in which Figure'v 1 is ,auf elevation and plan, partially sec.

Figure 2, `flat and edge view of strap, showing 4Figure 13,/ view `ofbag, with` strap and lock a e @viewer mount of bag, with leatherhinddus; l

Figure 5, `details of' the bolt; Figure 6, section, showing the straplocked; and. l Figure 7, plan of strap, as applied to mail-bag.

-My invention,` consists of a plate, having a tube exY tending throughit, at'or near its centre, perpendicul `lar to its plane, and havingarranged within it one or l more catches, which serve, in conjunctionwith arivet of lead, or other similar material, to form a sealllock -formail and other bags To enable others skilled in the art to make and useas hereinafter fully explained.

my invention, I will proceed todescribe its construction and operation.l Y

In the'drawingsj A indicates a bag, having a cord, leather strap, orother .suitable binding-G, around its mouth; B is a strap, provided atone end with a tongu-eless buckle or loop, C, and toward the other endwith a series of holes, `E F F; and between the buckle and `holes `alock,E, constructed as shown, in fig. 1, and attached as shown in iig.2; and I is a rivet or`bolt,

employed in connection with the lock, as hereinafter described.

` .The lock E is composed of a plate, e, havirig a tube, ,extendingthrough itat its centre, perpendic Within the late e are one Vtwo ormore sua 7 7 catches, fm m, bevelled at their 'adjacent ends, `andprojecting into the tube, springs n n being employed to force themforward;

. The rivet I is adapted to be thrust down intotube y e' until, just asits head rests ou the end of the tube,

the catches m m'spring into notches H H on the side f of it, and preventit from being withdrawn until the head is broken off. Itis made smallerat the neck.'

than elsewhere, so that the head can be cut or broken oi withoutdifficulty, and that any attempt to remove.

the rivet will result in the detachment of-the head. Its` head may bestamped or marked with any numbers, letters, or seal desirable for anyparticular purpose. y i

The material of the rivet is lead, tin, zinc, pewter, type-metal, orother suitable metal or material.

Thus 'constructed,lthe' strap is placed around the neck of the bag. Itsloose end is passed through the tongueless buckle or loop C. Itis thenturned backward andv tightened, so that the tube e will project pthrough one of the holes F, as shown iu tig. 6 The rivet I is theninserted into the tube, and pressed down tillitshead .rests upon the endofdthe tube and upon theY surface of the strap, in which position thecatches snap into the notches H H, and confine the rivet in theV tube,so that it cannot be removed until its head is broken ofi'. 4

A tag or label, D, maybe attached to the strap before itis fastened inthe manner abovedescribed, for any purpose required. l

The rivets I I are made in any quantity required, and are differentlystamped and marked, so that they cannot be easily duplicated.

-lhe marks, stamps, or seals may not only be placed upon their head, butupon their sides, ends, or elsewhere. t

'When used by the postofcedepartmeut, a numb'er or numbers may be added,showing where the bag has been made up and sealed.

` I am aware that a. locking-bolt, having arranged,

within an opening in itspointed end, two springcatches, in connectionwith which a steel key, resembling my rivet in form, is intended tol beused; has

been invented by another and I thereforewish it to' be understood that Imake no claim to suchinvention; but havingthus described my invention,

What I claim as new, and desire to secure by Letthe purposes hereinspeciied.

Y -JOHN DEWE.
